While many of its telosaur relatives developed long snouts and thin teeth for catching and eating fish, Lemmysuchus went in its own direction. The creature’s 3-foot-long skull evolved to have a broad snout and large teeth to crush the shells of turtles and other prey, the museum said.

Although the croc specimen was found a century ago, it was incorrectly cataloged at the time. A more recent look at the fossils revealed a previously unknown creature, and that meant it needed a new name.
